Mr. Mark Kelley, Vice President of Engineering of Longmont based DFM
Engineering, Inc., celebrates his 35th Anniversary on January 1, 2017.

Mark Kelley is
responsible for designing telescope control system software. His expertise is extensive.

He works closely with customers in determining control room specifications, computer requirements
and implementation and installation of DFM's Telescope Control System (TCSGalil™).

He specializes in mechanical and software design and testing,
instrument performance with detailed documentation, electronic fabrication supervision, and installation
administration.

Mr. Kelley is instrumental in designing, building, testing,
and retrofitting telescopes at DFM Engineering. The Computer Control System (TCSGalil™) developed and perfected
by Mr. Kelley is incorporated into many electro-optical mechanical instruments manufactured and
installed by DFM Engineering, Inc.

Mr. Kelley's first project with DFM Engineering was to provide Mechanical Engineering services for
a very large telescope project: the 2.4 Meter Hiltner telescope located at Kitt Peak, AZ. He also
assisted in the installation.

In June 2015, he led the DFM team of technicians in the installation of the 1.3m MCAT telescope designed by DFM for NASA on the remote Ascension Island in the Atlantic.

In June 2016, Mark Kelley and Dr. Frank Melsheimer completed the retrofit of the 1.2m Kryonerion telescope in the National Observatory of Athens, Greece. The retrofit included a Prime Focus Dual Imaging Instrument designed by Dr. Frank Melsheimer.

Mr. Kelley is instrumental in the success of DFM Engineering and is very much appreciated.
